`To aZ-Z whomtt may concern Be it known that I, LEUPONDELICK, a citizen ofthe" United States of America, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in lRoller- Bearings, of which the following is a specifil of one ofthe end cages, detached.

-appear'.

This invention relates more especially to that type of roller bearings'in which the rollers are of a cylindrical form and are held in proper parallel relation andagainst` endwise displacement by retaining end rings or caps. And the present improvement has for its object, to provide a simple and eilicient structural formation of the end retaining rings or cages, wherein the series of bearing rollers are effectively held in assembled relation and against accidental separation, as well as maintained in their usual parallel relation and from endWise .displacement, all as will hereinafter more .fully In the accompanying drawings: Figure 1, is a plan view of the` roller bearing detached, parts being shown broken away and in section to, illustrate the details 'of construction of the present invention. Fig.

2, is a view, partlyin end elevation, and

Fig. 1. Fig. 3, is a detail section on line .r2-m2, Fig. 1. Fig. 4, is a perspective view Similar reference numerals 1n parts 1n the several views.

dicate -like Referring to the drawings, 1 represents `the circular cluster of cylindrical bearing rollers formed with the usual convex ends and with circumferential recesses 2, 'adjacent to said convex ends a's shown.

3 is the .usual outer bearingsleeve, and 4 the shaft or axle of the bearing.

5 are the flat annular lor ringshaped body portions' of the pair of end retaining'caps of the present construction, and which are. adapted' to receive the end thust of the convex ends of the bearing rollers 1 and prevent undue individual longitudinal movement thereof.. And-as usual in the present class of bearings.,the radial thickness of said annularbody portion 5, is less than the diameter of the bearing rollers 1, in order that said rollers may project to the out side of the periphery, and to the inside of the bore, of said vbody portion to attain an unimpeded bearing of the rollers upon the Specication of Letters 4Patent.v

outerand'i'nne'r, circular track-ways lprovided by the bearing sleeve 3 and axle 4 aforesaid.

u l6 are circular-clusters or series of inset spacing tongues formin an integral part of the body portions 5 o lthe retaining caps,

' and corresponding in number with that of the lhearing rollers 1, and alternating therewith toy impose the requiredV parallel and The tongues '6 are approximately triangular in form andare 4spaced awayfrom the annular body portion 5, a distance equal to that from the 'ends ofthe rollers 1 to the peripheral grooves I2 of the c same, and are adapted to engage insaid grooves. In the vpresent improvement said spacing tongues' 6 are in parallel relation totheir respective annular body .portions 5, and are connected thereto by'narrow peripheral bars '7 arranged longitudinally, and which are adapted to connect the louter portions of said spacing tongues to the marginal portion of the annular body portions. in a ymanner which permits of said tongues being bent or sprung in any required direction in the .hereinafter described assembly of the roller `bearing parts.

In this connection a material part of the present invention com prises the formation of holding recesses 8, preferably of the concave form shown, in the opposite sides of the inset spacing tongues 6, aforesaid, so that the holding 'i recesses 8 of any vtwo adjacent tongues will coact to form an' enlarged intermediate cavity `into which is forced thev reduced neck formed in a bearing roller by the peripheralv recess 2, and so that the said roller will be held in assembled relation until forcibly separated. `Prior-'to an assemblage of the pair of end cages and the series of bearing rollers, the series of spacing tongues 6 are spreadapart by an outward bending of their ductile connecting necks 7 to widen the distances betweenl the series of opposite holdling recesses 8, and so that the neck formed on the bearing rollers 1 -by the circumferential recesses 2. may be disposed within the aforesaid holding recesses 8. With the parts so positioned, the series of spacing tongues 6 are forced toward the central axis of the bearing to effect a narrowing in the distance between the series of opposed holding recesses 8, so the same will close upon the aforesaid necks of the bearing rollers to hold the same in proper position and pref' thel described small and diametrically eX-.j tending cylindrical orifices givevery efec vent subsequent separation) of the rollers.- during handling, shipment,v etc., of theap-l pliance.

9 are a series of cylindrical oriiices ofa length more than double their diameterA eX- ,tending diainetrically v through thesolid:

bodies of theibearing rollersl and adapted to receive and hold by capillary attraction a convenient supply of lubricant. From extended practical test it has been found that tive resultsover chambers formed in the in- Y teriorof a roller and having aseriesof small outletapertures, and that 'the' lubricant is Yvery evenly supplied from alternate' ends of the-orifice in continued use.- I

2. In a roller bearing, the combination of l a series of bearing rollers provided with peripheral grooves near their ends, vand 'a retaining cage for said rollers com rising an annular plate member against which the Irollers have endwise abutment, a plurality Tof thin flexible bars extending laterally from the aforesaid annular member and disposed at' the periphery thereof and a plu?` rality of inwardly extending spacing .tongues of an approximately triangular form carried on the free ends of the aforesaid bars and adapted to be moved inwardly into the peripheral grooves of the bearing rollersby the inward iexure' of the bars aforesaid, the said tongues having holding recesses formed in their opposite edges.
